Q51. An engineer is attempting to improve OSPF network performance and discovers that the entire SPT recomputes.whenever a type 1 or type 2 LSA is received within an area.
Which action can optimize SPT operations?
A. Tune LSA throttling thresholds.
B. Enable incremental SPF.
C. Configure totally stubby areas throughout the domain.
D. Summarize networks on all ABRs.
Answer: B
Q52. When designing remote access to the Enterprise Campus network for teleworkers and mobile workers, which of the following should the designer consider?
A. It is recommended to place the VPN termination device in line with the Enterprise Edge firewall, with ingress traffic limited to SSL only
B. Maintaining access rules, based on the source IP of the client, on an internal firewall drawn from a headend RADIUS server is the most secure deployment
C. VPN Headend routing using Reverse Route Injection (RRI) with distribution is recommended when the remote user community is small and dedicated DHCP scopes are in place
D. Clientless SSL VPNs provide more granular access control than SSL VPN clients (thin or thick), including at Layer7
Answer: D
Q53. A network design engineer has been asked to reduce the size of the SPT on an IS-IS broadcast network. Which option should the engineer recommend to accomplish this task?
A. Configure the links as point-to-multipoint.
B. Configure QoS in all links.
C. Configure a new NET address.
D. Configure the links as point-to-point.
Answer: D
Q54. Which three statements about firewall modes are correct? (Choose three.)
A. A firewall in routed mode has one IP address.
B. A firewall in transparent mode has one IP address.
C. In routed mode, the firewall is considered to be a Layer 2 device.
D. In routed mode, the firewall is considered to be a Layer 3 device.
E. In transparent mode, the firewall is considered to be a Layer 2 device.
F. In transparent mode, the firewall is considered to be a Layer 3 device.
Answer: B,D,E

Answer: C
Q57. Which of the following should the Enterprise Campus network designer consider with respect to Video traffic?
A. While it is expected that the sum of all forms of video traffic will grow to over 90% by 2013, the Enterprise will be spared this rapid adoption of video by consumers through a traditional top-down approach
B. Avoid bandwidth starvation due to video traffic by preventing and controlling the wide adoption of unsupported video applications
C. Which traffic model is in use, the flow direction for the traffic streams between the application components, and the traffic trends for each video application
D. Streaming video applications are sensitive to delay while interactive video applications, using TCP as the underlying transport, are fairly tolerant of delay and jitter
Answer: C
Q58. CoS is applied for Layer 2 markings in an Ethernet environment. Which protocol must be configured on the Layer 2 switch port for CoS to work?
A. MPLS
B. IEEE 802.1W
C. IEEE 802.1Q
D. IEEE 802.1S
Answer: C
Q59. The requirement for high availability within the Data Center network may cause the designer to consider which one of the following solutions?
A. Construct a hierarchical network design using EtherChannel between a server and two VDCs from the same physical switch
B. Utilize Cisco NSF with SSO to provide intrachassis SSO at Layers 2 to 4
C. Define the Data Center as an OSPF NSSA area, advertising a default route into the DC and summarizing the routes out of the NSSA to the Campus Core
D. Implement network services for the Data Center as a separate services layer using an active/active model that is more predictable in failure conditions
Answer: B
